One of the first phones I had was from 7/11 about 3 1/2 yrs ago (yeah I was a late adopter).
I can't remember the plan they had but it was crap, some months I was paying $250 because my minutes would run out and I would have to top them up. I recall putting $50 on it and was only credited $30 because I had gone over my allotted number of txts and 'owed' them money. Customer service was laughable, virtually no help at all. Eventually I had a supervisor tell me that these phones were only really meant to be used as emergency phones and that maybe I should go with another provider. The pros are the phones are cheap, you can now get sim cards for them and decide which zone you want your number in and the mins last one year if you don't use them.
That was my experience, don't know what it's like now.
I moved to Koodo and have been there ever since.
Good luck.
